Detailed explanation-1: -The primary function of the basement membrane is to anchor down the epithelium to its loose connective tissue (the dermis or lamina propria) underneath. This is achieved by cell-matrix adhesions through substrate adhesion molecules (SAMs).
Detailed explanation-2: -Basement membranes are composed of several specific molecules such as type IV collagen, laminin, proteoglycans and entactin/nidogen and are produced mainly by the endothelial cell layer.
Detailed explanation-3: -…as the basal lamina or basement membrane. This thin layer serves as a boundary with connective tissue and as a substrate to which epithelial cells are attached. This rests on a basement membrane closely anchored to the surface of the dermis.
